Easily share your Wi-Fi connection using a QR code 📱. This project uses Python and the qrcode library to generate a QR code containing the necessary credentials to allow a mobile device to automatically connect to a Wi-Fi network.
The QR code generated includes error correction level Q, which allows approximately 25% of the code to be restored if damaged or obscured.
To run this project, make sure you have the qrcode library installed:
pip install qrcodeA QR (Quick Response) code is a two-dimensional pictographic code known for its fast readability and relatively large storage capacity. The code is made up of black squares (modules) arranged on a white background and can store different types of data:
- Binary
- Alphanumeric
- Kanji symbols
- And more
The qrcode library provides four levels of error correction. These allow a QR code to remain scannable even if partially damaged:
| Constant | Correction Level | Description |
|---|---|---|
ERROR_CORRECT_L |
Low | Recovers ~7% of the data |
ERROR_CORRECT_M |
Medium (default) | Recovers ~15% of the data |
ERROR_CORRECT_Q |
Quartile | Recovers ~25% of the data |
ERROR_CORRECT_H |
High | Recovers ~30% of the data |
| In this project, we use ERROR_CORRECT_Q for a balance between reliability and QR complexity.
This app uses Tkinter to provide a graphical interface where users can enter Wi-Fi credentials and instantly generate a QR code ready to scan.
